Probably taking revenge from being banned from this year's T In The Park, ticket touts were selling pre-sale TITP 2007 tickets on eBay yesterday for the somewhat princely sum of £500.

The 30,000 advance tickets, which went on sale yesterday and sold out in 70 minutes, but opportunistic touts had more than 100 tickets up for sale for five times their face value only a few hours later.

Festival chief Geoff Ellis said: "The auction site say they are a legitimate marketplace for people who can't go to concerts. But people who buy tickets 360 days ahead and apparently can't go within 10 minutes of buying them make a mockery of that.

"Hopefully, this is the evidence the Government need to put a stop to touting on eBay. I feel sorry for genuine fans. I'm going to speak to my lawyer to see if we can take action against touts using our logo without permission."

More tickets for the festival will go on sale in February.
